The Green Connections Plan began in 2011, led by the non-profit organization Nature in the City in collaboration with city and community-based agencies. The big idea expands on what we traditionally think about transportation planning by "imagining a world in which cars share the road with birds, bees, butterflies, and bicyclists," explains Keenehan.

"Each route in the network is named after a native San Francisco 'Key Species' and is designed to incorporate 'Key Habitat' for that species," according to Keenehan.
